To all whom. it may concern Be it known that l, RICHARD H. Get,

a citizen of the United States, at Bellevue, in the county of Huron and tat/e of Ohio, have invented certain new and ful Improvements in Soil-Pnlveriaer lm 7 cation. D

My invention relates to improvements in soil pulverizing implements, and more pan ticularly to that class or type of earthworh-' ing implements commonly known as packers and mulchers in which front and rear gangs of parallel extending pnlverizer .disks are em loyed, the ends of the axles of the front an rear gangs being mounted in and connected by reciprocate gen bearing members or yokes mo'yvably and sliclably con nected to the main! implement or draft frame.

The primary object of the invention is to provide a new implement of the class mentioned, whichwill not only be simple in construction and efiicient in operation, but will possess reat strength and which will reduce the liabl ity to disarrangement or injury to the parts to a minimum.

A further" and vory important object is to furnish a new constructionand arrangement of the gang connecting yolres, together with a floating arrangement of such gang connecting yokes with respect to the main frame. v

A further object is to so mount the gang yokes in the draft frame through the medium of guide members and rollers so that the draft will be transmitted in an im-' proved manner to the front and rear gang axles and disk gangs and at the same time permit the frontv and rear gangs of pulverizer disks to reciprocate or move in adjusting or conforming themselves to varyinginequalities of the ground or surface being cultivated, the connections being such also that the draftstresses will be equalized at ,all times on such front and rear gangs of pulverizer disks in the varying positions of the latter.

It is an important object of m invention to provide a floating arrangement of the axles and gangs of rollers which are designed to move over the contour of the terrain in such a way as not to affect the main frame as the floating frame conforms to these several contours of the ground. It

elements, of which the followingis a speciis an object to provide such an arrange ment that there will he no positive connection; between the floating frame and the mom frame but that the dentin frame may be allowed to reciprocate free y and independently of the main frame and only to be dguided by the main frame through the me mm of the sliding contacts and the rollers. It is a further. objectof the invention to provide an arch shaged member that Wlll reciprocate ahouta point removed from the main frame.

It is, a further object to provide a ready means of disassembling the various parts associated with the floating arch so that they can be renewed when they become worn.

With the above mentioned and other ends in view, the invention 'cons'istsxin the novel construction, arrangement and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanymg drawings and particularly pointed out in the appended claims.

Referring-to the drawings forming a part of this specification, Fi re 1 is a front elevation of a soil ulverizer implement :constructed in accordance with this invention, central portions of the disk gangs being broken away and some-of the central front pulveriz'er disks being removed for the par pose of clearer illustration of the parts.

Fig. 3, a side elevation of one of the draft frame end brackets, the gang yoke and yoke .1

side members and bearings therefor being removed. Fig. i, an end elevation of the same, the gang yoke guide retainer or bracket-being restored.

Fig. 5, a side elevation of one of the gang yokes detached, the gang axle shafts and the shaft and dust excluding end caps being removed. 1

Fig. 6, a dissembled sectional view of one ca s. V

lhc main or draft frame may be of any suitable and convenient constructlon, comold on his The end brackets l, terminate at their lower ends in heads 1*, said heads 1 being provided with guides l, in the present instance in the'specific. form of friction shoes adapted to slidably engage with the lower sides of the gang 'yolres hereinafter descr1bed.-

. .The implement is adapted to be drawn by means of acentrally located drart oar tongue 3, as shown in Fig. 2 of the drawings.

The improved implement preferably cornprises front and rear gangs of soil pulverizer disks 4 and 5, respectively, the front pulverizer. disks 4, being preferably larger in diameter than the rear disks 5, and as a means of so. mounting the front and rear disk gangs t and 5, as to permit an oscillatory or undulatory movement of such gangs to conform to or meet the varying contour of the surface being cultivated, front and rear axle shafts 6 and 7', respectively,

are provided, the disks 4 and e, being pref? crab y 1 provided with suitable openings forming bearings and being loosely mounted on the shafts 6 and 7, and the shafted and '2', areeonnectedat their ends by means of gain. yolres 8, said gang-yokes 8 being pref crab y of arcuate form and provided at their ends with hearing heads 8, provided with openings adapted to removably' receive and contain suitable bearing bushings 8", to removably receive and contain the ends of the 1 axle shafts 6 and 7. The shafts may be retained by means of retainer caps 8, and as a means of excluding dust and other foreign substances from the ends of thebearings the gen yoke heads 8, are preferably provided wit dust excluding caps 8 As a means of'providing suitable anti friction guides for "the tops of the gang yokes 8, and for permitting the latter to ride freely thereunder in the reciprocatory movement of the same, anti-friction guide rollers 9, are mounted at the sides of the draft frame members 1, on suitable axle bolts 9, and as a means of securing said guide rollers 9, in position and particularly as a means of removably rnountin the gang yolres 8, be

, neath the guide in ers 9, and above the till titlguide shoes 1, suitable guide members or yolre retainers 9 are provided, said guide members, in. the present instance, being in the specific form of V-shaped brackets and secured at their upper ends by means of attaching bolts and nuts l0, and at their lower ends by means of attaching elements ll. 8 designatesthe point removed from the frame about which the gang yolres 8 move.

lltwill be seen that the guide members 1', 9 3 securely retain the gang yokes- 8, in proper positionas against relative lateral. displacement and sidethrust, the guide members or yoke retainers 9", being also additionally secured by means of nuts Q, on the axle bolts 9 l-laving thus described one of the embodiments of my invention, without having attempted to set forth all the forms in which it may he needs, or all the modes of its use, what l claim and desire to secure by Letters Patent, o
